type DaTong 

type DaTong struct {
	// contains filtered or unexported fields
}

DaTong wacom

func New 

func New(config *params.DaTongConfig, db ethdb.Database) *DaTong

New wacom

func (*DaTong) APIs 

func (dt *DaTong) APIs(chain consensus.ChainReader) []rpc.API

APIs returns the RPC APIs this consensus engine provides.

func (*DaTong) Author 

func (dt *DaTong) Author(header *types.Header) (common.Address, error)

Author retrieves the Ethereum address of the account that minted the given block, which may be different from the header's coinbase if a consensus engine is based on signatures.

func (*DaTong) Authorize 

func (dt *DaTong) Authorize(signer common.Address, signFn SignerFn)

Authorize wacom

func (*DaTong) CalcDifficulty 

func (dt *DaTong) CalcDifficulty(chain consensus.ChainReader, time uint64, parent *types.Header) *big.Int

CalcDifficulty is the difficulty adjustment algorithm. It returns the difficulty that a new block should have.

func (*DaTong) Close 

func (dt *DaTong) Close() error

Close terminates any background threads maintained by the consensus engine.

func (*DaTong) Finalize 

func (dt *DaTong) Finalize(chain consensus.ChainReader, header *types.Header, statedb *state.StateDB, txs []*types.Transaction, uncles []*types.Header) error

func (*DaTong) FinalizeAndAssemble 

func (dt *DaTong) FinalizeAndAssemble(chain consensus.ChainReader, header *types.Header, statedb *state.StateDB, txs []*types.Transaction, uncles []*types.Header, receipts []*types.Receipt) (*types.Block, error)

Finalize runs any post-transaction state modifications (e.g. block rewards) and assembles the final block. Note: The block header and state database might be updated to reflect any consensus rules that happen at finalization (e.g. block rewards).

func (*DaTong) PreProcess 

func (c *DaTong) PreProcess(chain consensus.ChainReader, header *types.Header, statedb *state.StateDB) error

PreProcess update state if needed from various block info used with some PoS Systems

func (*DaTong) Prepare 

func (dt *DaTong) Prepare(chain consensus.ChainReader, header *types.Header) error

Prepare initializes the consensus fields of a block header according to the rules of a particular engine. The changes are executed inline.

func (*DaTong) Seal 

func (dt *DaTong) Seal(chain consensus.ChainReader, block *types.Block, results chan<- *types.Block, stop <-chan struct{}) error

Seal generates a new sealing request for the given input block and pushes the result into the given channel.

Note, the method returns immediately and will send the result async. More than one result may also be returned depending on the consensus algorothm.

func (*DaTong) SealHash 

func (dt *DaTong) SealHash(header *types.Header) (hash common.Hash)

SealHash returns the hash of a block prior to it being sealed.

func (*DaTong) SetChainConfig 

func (dt *DaTong) SetChainConfig(chainConfig *params.ChainConfig)

func (*DaTong) SetStateCache 

func (dt *DaTong) SetStateCache(stateCache state.Database)

func (*DaTong) VerifyHeader 

func (dt *DaTong) VerifyHeader(chain consensus.ChainReader, header *types.Header, seal bool) error

VerifyHeader checks whether a header conforms to the consensus rules of the stock Ethereum ethash engine.

func (*DaTong) VerifyHeaders 

func (dt *DaTong) VerifyHeaders(chain consensus.ChainReader, headers []*types.Header, seals []bool) (chan<- struct{}, <-chan error)

VerifyHeaders is similar to VerifyHeader, but verifies a batch of headers concurrently. The method returns a quit channel to abort the operations and a results channel to retrieve the async verifications.

func (*DaTong) VerifySeal 

func (c *DaTong) VerifySeal(chain consensus.ChainReader, header *types.Header) error

VerifySeal implements consensus.Engine, checking whether the signature contained in the header satisfies the consensus protocol requirements.

func (*DaTong) VerifySeal2 

func (dt *DaTong) VerifySeal2(chain consensus.ChainReader, header, parent *types.Header) error

func (*DaTong) VerifyUncles 

func (dt *DaTong) VerifyUncles(chain consensus.ChainReader, block *types.Block) error

VerifyUncles verifies that the given block's uncles conform to the consensus rules of the stock Ethereum ethash engine.
